I'm a clumsy, cowardly and unlucky guy, probably will end up bitten or devoured. Plus I'll probably have to help people, can't just let them get devoured as well so I might end up sacrificing myself. I can only see myself surviving if I manage to secure and fortify an area, however small it is, then I can continue expanding my territory. It'll also only last if I have a trustworthy group and enough survival experience and skills to defend against not only zombies but hostile or desperate people as well. And this also doesn't factor in a military coming in and indiscriminately killing everything in sight which is a worse case scenario. Or a giant zombie horde attacking. Both scenarios, I would be done for.
So yeah my chances of survival are very dim and I don't see myself having the luck and plot protection like characters in a zombie fiction have.
How long do you think you would survive in the even that your government collapses and total anarchy occurs?
